TRANSFER SWITCH

CONTROLLER

WITH UNINTERRUPTED TRANSFER AND MULTIPLE GENSET SUPPORT

The DKG-329 is designed to monitor 3-phase

mains voltages, send remote start command to

generating sets and control the changeover of both

generator and mains contactors.

The unit offers an internal synchroscope for

uninterrupted transfer in both directions. The

number of gensets to run before transfer is

selectable, allowing multiple genset support.

If a fault condition occurs, the unit disables the

remote starting automatically and indicates the

failure with the corresponding led lamp and text.

The unit provides a comprehensive set of digitallyadjustable program parameters. The unauthorizedaccess to program parameters is prevented by a 3level password system. All programs may bemodified via front panel pushbuttons and do notrequire any external unit.

Last 100 faults are stored in the event log file. The

event log includes not only the date-time

information, but also a comprehensive list of

measured parameters at the time that the fault has

occurred.

The WINDOWS based RAINBOW programallows remote monitoring and control.

The unit supports MODBUS protocol enablingcommunication with PLCs and buildingmanagement systems. The MODBUS protocol isalso supported through GSM and PSTNmodems.

The unit is a control and protection panel designed to monitor the 3-phase mains voltages, send remote

start command to the generating set and make changeover of both generator and mains contactors. The genset is

supposed to be controlled by a Remote Start type control unit.It shows the measured values on its display. The

unit is designed to provide user friendliness for both the installer and the user. Programming is usually

unnecessary, as the factory settings have been carefully selected to fit most applications. However

programmable parameters allow the complete control over the load transfer. Programmed parameters are

stored in a Non Volatile Memory and thus all information is retained even in the event of complete loss of

power.

Measured parameters are:

Alarms indicate an abnormal situation in the generating set are divided into 3 priority levels:

1- ALARMS:These are the most important fault conditions and cause:

- The ALARMled to be on steadily,

- The genset contactor to be released immediately,

- The engine to be stopped immediately,

- The Horn, Alarm,Alarm+Load_dumpand Alarm+Load_dump+Warningdigital

outputs to operate, (if selected via programming menu)

2- LOAD_DUMPS:These fault conditions cause:

- The ALARM led to flash,

- The genset contactor to be released immediately,

- The engine to be stopped after Cooldown period,

- The Horn, Alarm+Load_dumpand Alarm+Load_dump+Warningdigital outputs to

operate, (if selected via programming menu)

3- WARNINGS: These conditions cause:

- The WARNING led to be on steadily,

- The Hornand Alarm+Load_dump+Warningdigital outputs to operate, (if selected

via programming menu)

If the ALARM MUTE button is pressed, the Horn output will be deactivated; however the

existing alarms will persist and disable the operation of the genset.

Alarms operate in a first occurring basis:

-If an alarm is present, following alarms, load_dumps and warnings will not be accepted,

-If a load_dump is present, following load_dumps and warnings will not be accepted,-If a warning is present, following warnings will not be accepted.

Alarms may be of LATCHING type following programming. For latching alarms, even if the alarm

condition is removed, the alarms will stay on and disable the operation of the genset. The existing alarms

may be canceledby pressing one of the operating mode buttons (LOAD TEST / TEST / OFF / AUTO).

Most of the alarms have programmable trip levels. See the programming chapter for adjustable

alarm limits.

EMERGENCY STOP:Set if a signal is detected at the emergency stop input.

SPARE-1 / SPARE-2:Set if a signal is detected from the related spare fault input.

MAINS CB FAIL TO CLOSE (warning): Set if the mains contactor feed back input is not active at the end

of mains contactor timeout when mains contactor is activated. Enabled if one of digital inputs assigned as

mains contactor feed back input.MAINS CB FAIL TO OPEN (load_dump): Set if the mains contactor feed back input is still active at the

end of mains contactor timeout when mains contactor is deactivated. Enabled if one of digital inputs

assigned as mains contactor feed back input.

GENSET CB FAIL TO CLOSE (warning):Set if the genset contactor feed back input is not active at the

end of genset contactor timeout when genset contactor is activated. Enabled if one of digital inputs

assigned as genset contactor feed back input.

GENSET CB FAIL TO OPEN (warning):Set if the genset contactor feed back input is still active at the

end of genset contactor timeout when genset contactor is deactivated. Enabled if one of digital inputs

assigned as genset contactor feed back input. The mains contactor cannot operate when this warning is

up.

LOW SPEED / HIGH SPEED: Set if the generator frequency is outside programmed limits. These faults

will be monitored with Holdoff Timerdelay after the engine is running. Low and high limits for warning andalarm are separately programmable. Another high frequency shutdown limit which is 12% above the high

limit is always monitored and stops the engine immediately.

4. ALARMS AND WARNINGS


11/43

DKG-329 User Manual V-12 (09.10.2012)

- 11 -

STOP FAIL (warning):Set if the engine has not stopped before the expiration of the Stop Timer.

OVERLOAD (load_dump):Set if at least one of the genset phase currents goes over the Overcurrent

Limit for Overload Timer. If currents goes below the limit before expiration of the timer then no alarm will

be set.

EXCESS POWER (load_dump):Set if the genset power (kW) supplied to the load goes over the Excess

Power limit for Overload Timer. If the power goes below the limit before expiration of the timer then no

alarm will be set.GENSET LOW VOLTAGE:Set if any of the generator phase voltages goes outside programmed limits for

Overload Timer. This fault will be monitored with holdoff timerdelay after the engine is running.

GENSET HIGH VOLTAGE:Set if any of the generator phase voltages goes outside programmed limits for

Overload Timer. This fault will be monitored with holdoff timerdelay after the engine is running.

LOW BATTERY VOLTAGE (warning):Set if the battery voltage goes below the programmed limit.

HIGH BATTERY VOLTAGE:Set if the battery voltage goes above programmed limits. Both warning and

alarm levels for high battery voltage are programmable.MAINS PHASE ORDER FAIL (warning):Set if the mains phase order checking is enabled, mains phasesare present and mains phase order is reversed. This fault prevents the Mains Contactor to close.

The modes of operation are selected by pushing the front panel keys. Changing the operation

mode while the genset is running will result to a behavior suitable for the new operating mode. For example,

if the LOAD TEST mode is selected when genset is running at TEST mode, then the load will be transferred

to the genset.

OFF: In this mode, the mains contactor will be energized if mains phase voltages are within the

programmed limits. The engine will be stopped.

AUTO:It is used for genset and mains automatic transfer. If at least one of the mains phase voltages is

outside limits, the mains contactor will be deactivated and the REMOTE START output will be activated atthe end of the start wait period. The engine will run without load during engine heating period. After this, if

alternator phase voltages and frequency are within limits, then the unit will wait for the generator contactor

period and the generator contactor will be energized.

When all the mains phase voltages are within the limits, the engine will continue to run for the mains waiting

period. At the end of this period the generator contactor is deactivated and the mains contactor will be

energized. If a cooling period is given, the REMOTE START output will be active during the cooling period.

At the end of the period, the REMOTE START output will be de-energized and the diesel will stop. The unit

will be ready for the next mains failure. If the operation of the genset is disabled by the weekly schedule,

then the AUTOled will flash, and the operation of the genset will be as in the OFFmode.

TEST: It is used to test the generator when the mains are on, or keep the generator running in the

emergency backup mode. The operation of the generator is similar to the AUTO mode, but the mains

contactor will not be deactivated if the mains are not off. If the mains are off, mains contactor will bedeactivated and the generator contactor will be activated. When the mains are on again, a changeover to

the mains will be made, but the engine will be kept running unless another mode is selected. To stop the

engine, select AUTOor OFFmode.

LOAD TEST:It is used to test the genset under load. Once this mode is selected, the engine will run and

the load will be transferred to the genset. The genset will feed the load indefinitely unless another mode is

selected.

5. MODES OF OPERATION


12/43

DKG-329 User Manual V-12 (09.10.2012)

- 12 -

The unit has two ways of transferring the load from genset to mains and vice versa.

These modes are:

-transfer with interruption.-no break transfer.

This is the most conventional way of transferring the load between the genset and mains. Therewill be a power interruption period duration during the transfer. Note that the program parameters MainsContactor Timerand Genset Contactor Timerdefine the power interruption period.

Transfer from genset to mains:-The generator contactor releases,-The unit waits for Mains Contactor Timer-The mains contactor is energized.

Transfer from mains to genset:-The mains contactor releases,-The unit waits for Genset Contactor Timer

-The generator contactor is energized.

In this mode, the transfer will be made without power interruption. This implies that both ofthe mains and generator contactors will be active during transfer.

The maximum duration that both contactors will be activated is programmable. However thisprocess may be quicker with the use of one auxiliary contact at each contactor. Thus the changeoverwill be quite instantaneous, preventing any excess or reverse power condition. Any digital input can beprogrammed for genset contactor auxiliary contact and mains contactor auxiliary contact.

To prevent a phase to phase short circuit below criteria must be met:

-The mains and generator voltages must be equal,-The mains and generator voltages must have the same phase,-The mains and generator voltages must have the same phase sequence order.

The unit will allow a No Break Transferonly if all of the below conditions are fulfilled:

-Mains phase voltages within the programmed limits,-Mains frequency within the programmed limits,-Genset phase voltages within the programmed limits,-Genset frequency within the programmed limits,-Mains phase order correct (or phase order check must be disabled),-Genset phase order correct (or phase order check must be disabled),-The difference between mains and genset frequencies not more than programmed limit,-The voltage difference between mains_L1 and genset_L1 not more than programmed limit,

-The phase angle between mains_L1 and genset_L1 not more than programmed limit,

If this transfer method is used, it is advised to make an electricalinterlock between contactors to prevent a phase to phase shortcircuit.

When a No Break Transfer cycleis initiated, the unit checks all the above criteria to besatisfied as long as the Synchronization Fail Timeout is not expired.

Normally with frequencies matching at +/- 2Hz and voltages matching at +/-10 volts anuncontrolled No Break Transferwill be successfull.

If synchronization conditions are not met at the expiration of the Synchronization Fail

Timeout, then the unit reverts to a Transfer with Interruption.

If matching is found before the expiration of the Synchronization Fail Timeout,then both

contactors will be activated. If contactor auxiliary contacts are used, the other contactor will releaseimmediately. If contactor auxiliary contacts are not used, the other contactor will release after contactortimeout.

The unit has a set of programmable parameters to define the No Break Transfer operation.These parameters are:

Mains Voltage Low Limit (Electrical Parameters):Each of the mains phase voltages must be overthis limit.

Mains Voltage High Limit (Electrical Parameters):Each of the mains phase voltages must be belowthis limit.

Mains Frequency Low Limit (Electrical Parameters):The mains frequency must be over this limit.

Mains Frequency High Limit (Electrical Parameters):The mains frequency must be below this limit.

Genset Voltage Low Limit (Electrical Parameters):Each of the genset phase voltages must be overthis limit.

Genset Voltage High Limit (Electrical Parameters):Each of the genset phase voltages must bebelow this limit.

Low Frequency Shutdown (Engine Parameters):The genset frequency must be over this limit.

Low Frequency Warning (Engine Parameters):The genset frequency must be over this limit.

High Frequency Shutdown (Engine Parameters):The genset frequency must be below this limit.

High Frequency Warning (Engine Parameters):The genset frequency must be below this limit.

Genset Phase Order Enable(Electrical Parameters):If set , this parameter will enable the phaseorder check for genset. The phase order check should be disabled only in single phase gensets.

Mains Phase Order Enable(Electrical Parameters):If set, this parameter will enable the phase ordercheck for mains.

No Break Transfer(Controller Config Parameters):This parameter enables/disables the No BreakTransfer feature.

Max Frequency Difference(Controller Config Parameters): This is the maximum difference betweenmains and genset frequencies to enable a NO Break Transfer.

Max Voltage Difference(Controller Config Parameters): This is the maximum difference between the

mains_L1 and genset_L1 voltages to enable a NO Break Transfer.

Max Phase Difference(Controller Config Parameters):This is the maximum phase differencebetween the mains_L1 and genset_L1 to enable a No Break Transfer.

Synchronization Fail Timeout (Controller Config Parameters):If the phase and voltagesynchronization is not successful before the expiration of this timer, then the unit terminates the NoBreak Transferand makes a Transfer with Interruption.

Contactor Timeout (Controller Config Parameters):This is the maximum time duration in which bothcontactors are active in case of No Break Transfer.

Any digital input may be assigned as mains and genset contactor feedback input for faster transfer.For this, digital input function select parameter groupis used to select the function and inputconfiguration parameter groupis used to configure digital inputs. The action parameter should be

set to 3and always active option should be selected for both contactor feedback inputs. NCtypemust be selected for mains contactor feedback input.(Pls refer to programming chapter for moredetailed explanation)

The unit offers the possibility of REMOTE STARTmode of operation. Any digital input may beassigned as Remote Start Inputusing Input Function Selectprogram parameters.

The REMOTE START signal may be a NO or NC contact, switching to either battery positive orbattery negative. These selections are made using programming menu.

It is also necessary to set the ACTIONprogram parameter of the related input to 3in order toprevent any alarm from this input.

In this mode the mains phases are not monitored. If the REMOTE START signal is present thenthe mains will be supposed to fail, inversely if the REMOTE START signal is absent, then mainsvoltages will be supposed to be present. The front panels mimic diagrams mains LEDs will reflect the

status of the REMOTE START input.

The unit offers an optional SIMULATE MAINSsignal input. Any digital input may be assignedas Simulate Mainsusing Input Function Selectprogram parameters.

It is also necessary to set the ACTIONprogram parameter of the related input to 3in order toprevent any alarms generated from this input.

The SIMULATE MAINS signal may be a NO or NC contact, switching to either battery positive orbattery negative. These selections are made using the programming menu.

If the Simulate Mainsinput is defined and the input signal is active, the mains phases are notmonitored and supposed to be inside limits. This will prevent the genset from starting even in case of amains failure. If the genset is running when the signal is applied, then usual Mains Waiting andCooldown cycles will be performed before engine stop. When the SIMULATE MAINS signal is present,the front panels mimic diagrams mains LEDs will reflect the mains voltages as present.

When the signal is passive, the unit will revert to normal operation and monitor the mainsvoltage status.

The REMOTE START operation overrides SIMULATE MAINS andFORCE TO START operations.

The Delayed Mains Simulation feature is used in battery backed up telecom systems wherebatteries are able to supply the load during a certain period. The genset is requested to run only whenbattery voltage drops below the critical level. Once the engine runs, the rectifier system starts chargingthe batteries and the battery voltage goes up immediately. Thus the engine should continue to run aprogrammed period for effective charging. The critical battery voltage level will be detected by anexternal unit which provides the digital Simulate Mains signal for the genset control unit.

The unit offers an optional SIMULATE MAINSsignal input. Any digital input may be assignedas Simulate Mainsusing Input Function Selectprogram parameters.

It is also necessary to set the ACTIONprogram parameter of the related input to 3in order toprevent any alarms generated from this input.

The SIMULATE MAINS signal may be a NO or NC contact, switching to either battery positive or

battery negative. These selections are made using the programming menu.

If the Delayed Simulate Mains program parameter is set to 1 and the input signal is active

when the genset is not feeding the load, the mains phases are not monitored and supposed to be insidelimits. This will prevent the genset from starting when the simulate mains signal is present (batteriescharged). The genset will start when mains voltages are out of limits and the simulate mains signal notpresent.

If the genset is running when the signal is applied, then MAINS SIMULATION will be preventedduring Flashing Relay Timer program parameter. After this, usual Mains Waiting and Cooldown cycleswill be performed before engine stop. When the SIMULATE MAINS signal is present, the front panelsmimic diagrams mains LEDs will reflect the mains voltages as present.

When the signal is passive, the unit will revert to normal operation and monitor the mainsvoltage status.

The REMOTE START operation overrides DELAYED SIMULATEMAINS operation. When both parameters Remote StartOperation and Delayed Simulate Mains are set then REMOTESTART operation mode is performed.

This led is designed to help the periodic maintenance of the genset to be made consistently.

The periodic maintenance is basically carried out after a given engine hours (for example 200

hours), but even if this amount of engine hours is not fulfilled, it is performed after a given time limit (for

example 12 months).

The unit has both programmable engine hours and maintenance time limit. The engine hours is

programmable with 50-hour steps, the time limit is programmable with 1 month steps. If any of the

programmed values is zero, this means that the parameter will not be used. For example a maintenance

period of 0 months indicates that the unit will request maintenance only based on engine hours, there will

be no time limit. If the engine hours is also selected as 0 hours this will mean that the SERVICE REQUEST

display will be inoperative.

When the engine hours OR the time limit is over, the SERVICE REQUEST led (red) will start to

flash and the service request relay function will be active.

The service request relay function may be assigned to spare relays using Relay Definition

program parameters. Also relays on an extension module may be assigned to this function.

The remaining engine hours and the remaining time limit are kept stored in a non-volatile memory

and are not affected from power supply failures.

The time and engine hours to service are displayed in the STATISTICAL COUNTERS menu.

The unit features a non-erasable incremental engine hour meter. The hour meter information is

kept in a non-volatile memory and is not affected from power supply failures.

The engine hours may be displayed STATISTICAL COUNTERS menu.

The date & time display is provided for verification.

To turn off the SERVICE REQUEST led, and reset the

service period, press together the ALARM MUTE andLAMP TEST keys for 5 seconds.

The SERVICE REQUEST led has no effect on the gensetoperation.

Some additional features are installed within consecutive software releases. In order to be sure

of the validity of the status of the unit, the software version needs to be known.

The software version of the unit is displayed together with the datatime information.

The software version consists of 2 numbers. The first number represent the operating software

version of the unit.

The unit is capable of making modem calls in case of alarm, as well as answering modem callsmade from a remote location. GSMmodems and classic cable network (PSTN) modems areacceptable.

If the modem is connected to the unit, the Modem Enableprogram parameter should be set to1, otherwise faulty operation may occur.

A maximum of 2 telephone numbers can be defined for outgoing modem calls. In case of alarm,the unit will attempt to reach control centers associated with each number. In case of modemconnection failure, the call will be repeated up to 30 times with 2 minute intervals.

When the modem call is in progress, a telephone icon ( ) will appear at the upper rightcorner of the screen.

Advised modems are DATAKOM types which are powered up from the same DC batteryvoltage than the unit. Most of other desktop modems with standard AT commands are also usable, but itis the users responsibility to provide an uninterrupted AC supply source to the modem. The necessarymodem cable will be supplied by DATAKOM.

Modem calls are always terminated by the central RAINBOW software. However the unit doesnot allow connection durations exceeding 2 minutes, and hangs up the modem when this periodexpires.

The PC program used for remote monitoring and programming is the same RAINBOW softwareused for RS-232 connection.

Please note that the modem operation is also compatible with the MODBUS communication.

Thus the unit can iniate and receive calls to/from a MODBUS master station. Please review chapter_8for more details on MODBUS communication.

If Modem Enableor SMS Enableor MODBUS Addressparametersare different from zero, the local PC connection will not work.

The GSM SMS sending is activated by setting the SMS Enableprogram parameter to 1.

When a fault condition occurs, the unit will compose an SMS message and will send it to up to 6phone numbers. If modem is enabled, only 4 telephone numbers are available for SMS sending.

The unit is also able to send SMS messages in below conditions, without creating a visible alarm orwarning:Mains Fail, Mains Restored(enabled via SMS on Mains Changeprogram parameter)

If both modem and SMS are enabled, the unit will send SMS messages first and attempt modemconnection afterwards.

When SMS sending is in progress, an (SMS) icon will appear at the upper right corner of thescreen.

The maximum number of alarms transmitted in a SMS message is 4. This limitation is due to themaximum length of an SMS message which is 160 characters.

A sample GSM SMS message is given below:

DKGxxx STOP : EMERGENCY STOP.END OF ALARM LIST

The first line of the message carries information about the unit type and the site identity string. Thisline is intended for the identification of the genset sending the SMS message.

Each following line will give one fault information. The message will always be terminated by theEND OF ALARM LIST string.

When the message is sent, the existing alarms will be masked, causing the audible alarm relay torelease and preventing consecutive GSM SMS messages. Any new upcoming alarm will result in a newGSM SMS message. The new message will indicate all existing alarms, even masked ones.

The necessary GSM modem cable will be supplied by DATAKOM. This is the same cable asPSTN (land) modems.

If Modem Enableor SMS Enableor MODBUS Addressparametersare different from zero, the local PC connection will not work.

The unit offers automatic exerciser operation. The exercise operation may be done on a daily,weekly or monthly basis.

The start day and time of the exercise is programmable as well as its duration. The exercisemay be done with or without load following programming.

Program parameters related to the exerciser are:Exercise start day and hourExercise durationExercise off_load/on_loadExerciser Period (Daily / Weekly / Monthly)

Please refer to the programming section for a more detailed description of the aboveparameters.

When the start day and hour of exercise has come, the unit will automatically switch to eitherTESTor LOAD TEST mode. The engine will run and if the on_load exercise is selected then the load

will be transferred to the genset.

If a mains failure occurs during the off-load exercise, the load will not be transferred to thegenset unless the Emergency Backup Operationis allowed by setting the related program parameterto 1. Thus it is highly recommended that the Emergency Backup mode enabled with off-load exerciser.

At the end of the exercise duration, the unit will switch back to the initial mode of operation.

If any of the mode selection keys are pressed during exercise, then the exercise will beterminated.

Using the daily exercise mode, the unit may feed the load from the genset during predefinedhours of the day. This operation may be used in high tariff periods of the day.

The load shedding feature consists on the disconnection of the least crucial loads when thegenset power approaches to its limits. These loads will be supplied again when the genset power falls

below the programmed limit. The internal Load Shedding function is always active. Any of the auxiliaryrelays may be used as the load shedding output.

The dummy load function consists on the connection of a dummy load if the total genset load isbelow a limit and to disconnection of the dummy load when the total power exceeds another limit. Thedummy load function is the inverse of the load shedding function, thus the same output may be used forboth purposes.

The parameters used in Load Shedding feature are in the Electrical Parameters Group:Load Shedding Low Limit:If the genset active power output goes below this limit, then the LoadShedding relay will be deactivated.Load Shedding High Limit:If the genset active power output goes above this limit, then the LoadShedding relay will be activated.

The unit offers possibility of updating the firmware in the field. The firmware is updated throughthe RS-232 serial port using Rainbow or a special DOS program.

The unit will go to firmware download mode with a special command from the PC program. Indownload mode, the display of the unit will show DL-V1.00

During firmware update process, the progress is visible through a completion bar on the screen.

The firmware update operation will take around 3 minutes.

After completion of the update a special command will set back the unit to normal operationmode.

The controller is able to provide a pre-transfer digital output function.

This function is designed for elevator systems, in order to bring the cabin to a floor and open cabindoors before transfer.

The duration where this output is active is adjusted with the Pre-Transfer Delayparameter.

The Pre-Transfer signal may be assigned to any digital output.

In most applications, the genset is requested to operate only in working hours. Thanks to theweekly program feature unwanted operation of the genset may be prohibited.

The unit has one programmable turn-on/turn-off time pairs for each day of week. Theseprogrammable parameters allow the genset to operate automatically only in allowed time limits.

The weekly operation schedule is only active in AUTOmode. In other modes it will not affectthe genset operation.

In AUTOmode, if the operation of the genset is disabled by the weekly schedule, then theAUTO led will flash(instead of a steady on state).

Each turn-on/turn-off time is defined in 10 minute steps.

Unused programs should be set to 24:00.

An example setup may be as follows:

Monday Turn_on 07:00

Monday Turn_off 18:00Tuesday Turn_on 07:00Tuesday Turn_off 18:00Wednesday Turn_on 07:00Wednesday Turn_off 18:00Thursday Turn_on 07:00Thursday Turn_off 18:00Friday Turn_on 07:00Friday Turn_off 18:00

Saturday Turn_on 07:00Saturday Turn_off 13:00

Sunday Turn_on 24:00 (Sunday no turn on time, last operation mode continues)

Sunday Turn_off 24:00 (Sunday no turn off time, last operation mode continues)

If the same time is used for turn on and turn off, then it will be considered as a turn-on time.

The unit has a battery backed-up precision real time clock circuit. The real time clock circuit willcontinue its operation even in power failures. The real time clock is precisely trimmed using the RealTime Clock Adjustprogram parameter. For more details check the programming section.

The genset operates while AC mains are OK or continues to operate after AC mains are OK:

-Check engine body grounding.-AC mains voltages may be outside programmed limits, measure the phase voltages.-Check the AC voltage readings by pressing the MENU button.-Upper and lower limits of the mains voltages may be too tight. Check the parameters Mains VoltageLow Limitand Mains Voltage High Limit. Standard values are 170/270 volts.-The hysteresis voltage may be given to excessive. The standard value is 8 volts.

AC voltages or frequency displayed on the unit are not correct:

-Check engine body grounding, it is necessary.-The error margin of the unit is +/- 3 volts.

-If there are faulty measurements only when the engine is running, there may be a faulty chargingalternator or voltage regulator on the engine. Disconnect the charging alternator connection of theengine and check if the error is removed.-If there are faulty measurements only when mains are present, then the battery charger may be failed.Turn off the rectifier fuse and check again.

kW and cos readings are faulty although the Amp readings are correct:

-Current transformers are not connected to the correct inputs or some of the CTs are connected withreverse polarity. Determine the correct connections of each individual CT in order to obtain correct kWand cos for the related phase, and then connect all CTs.

Short circuit the outputs of unused Current Transformers.

AUTO led flashes and the genset does not run when mains fail:

The unit is in Weekly Schedule OFF time. Please check date and time setting of the unit. Please checkalso Weekly Schedule program parameters.

The unit is inoperative:

Measure the DC-supply voltage between Bat+ and Bat- terrminals at the rear of the unit. If OK, turn allfuses off, then turn all fuses on, starting from the DC supply fuse. Then test the unit again.

Programming mode can not be entered:

The program lock input disables programming mode entry. Disconnect the program lock input frombattery negative before modification. Do not forget to make this connection again to preventunauthorized program modifications.

Some program parameters cannot be modified:

These parameters are reserved for factory setting and require a higher level password.
